2 Claims.

This invention relates to internal combustion engines and more specifically to engines of the Diesel type. a

In general, it is an object of the invention to provide a device of the character described which will efllclently perform the purposes for which it is intended, which is simple and economical of construction, which can' be expeditiously, conveniently and safely manipulated, and which can be readily manufactured and assembled.

Another object of the invention is to provide means for reciprocating and oscillating a plurality of sleeve valves in a single motor simultaneously and substantially without the use of gears; to provide-such mechanism which uses linkage connections; and to provide a single mechanism for motivating not only the slide valves but also the high pressure fuel pumps for the various cylinders.

Another object of the invention is to provide, as a combined unit, a Diesel precombustion chamber and a resilient safety valve therefor:

and to provide such a unit integral nozzle.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combination of elements and arrangement of fled in the construction hereinafter set forth and the scope of the application of which will .be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description, taken in connection with the accompanying drawings, in which:

Figure 1 is a view in elevation, with parts cut away and partially in section, of a machine embodying one form of the invention;

Fig. 2 is a cross-sectional view of the device shown in Fig. 1 and taken along the line 2-2 of Fig. 1;

Fig. 3 is a view in perspective of portions of the device shown in Fig. 1,;

Fig. 4 is a plan view of portions of the device shown in Fig. 1; and

Fig. 5 is a view in elevation of the upper part of one of the cylinders.

In the drawings, i0 denotes the outer casing with a fuel of a Diesel engine having an intake manifold l2 which leads to the various inders It. The latter are alike. There is a sleeve valve [8 slidable within the cylinder wall and having one or more air intake and one or more ports I of the cylparts which will be exempliexhaust ports l9 registerable with ports it, There is the usual piston 20 and piston rod 22 leading to main crank shaft 24.

A cylinder head 25 fits against the inner surface of the upper part of the sleevevalve and is held in place by the cylinder cap 28. There is a removable precombustion chamber 30 which is generally spherical and seats in a roughly cupshaped portion of the cylinder head. A safety compression release valve 32 seats in an exit passageway from the precombustion chamber. The valve is held in closed position by a spring 34 one end of which presses the valve into closed position and other end of which presses against a cap nut 36 screwed onto the cylinder head. A lever 38 is attached to an annular lifting cam 30. A rotation of the lever causes the release valve to be raised against the action of the spring whereby any compressed gas in the precombus: tion chamber may escape between the release valve and the cylinder head 25 to escape through vents 42 to the atmosphere.' There may be a connecting rod 44 attached to the various levers 38 for operating them simultaneously.

Means are provided for oscillating and reciproeating the sleeve valves. These means extend along the cylinders at one side of the engine. They do not include gearing other than incidentally as a means for the transfer of energy. This linkage system is shown in Figs. 2 and 3. The linkage system shown comprises a pair of connecting rods 52 extending laterally from cylinder to cylinder. Power from the main crank shaft is supplied to these rods by any convenient means such as a link belt-54 which delivers power to sprocket gear 56 on shaft 58. A forty-five degree beveled gear 60 attached to the latter meshes with a similar gear 62 on a shaft 68. The latter is conveniently directed perpendicularly toward the axis of one end cylinder I6. A crank pin 64 on gear 62 is attached to and causes the motion of one connecting rod 52.

The motion of the connecting rod 52 is transmitted to the sleeve valves l8 by respective suitable mechanisms. Those shown comprise, for each cylinder, to the connecting rod 52 and, at the other end, to crank shaft 68 fixed in housing 10. Attached to the shaft 68 is a cam 12 which also acts as a crank in that a sliding ball joint 14 is fixed to a boss 14a in'the face of the cam and connects with an extension 15. If desired, gear 62 may support boss-14a.

In order that there may be no trouble at dead center, there maybe a second or supplementary a crank rod 66 pivoted at one end of the supplementary rod 52 is fixed to a crank cheek l8 and the latter is rotatable about crank pin 64. Thus, when gear 62 moves, both connecting rods 52 move, the first connecting rod 52 being placed ninety degrees in advance of the second. I

A plunger 80 in a high pressure fuel pump 82 is connected at its outer end through suitable elements to cam 12 from which the plunger receives its motion. The various cams 12 are oriented to operate the various plungers'80 at the proper times for the supply of fuel to the various cylinders i6.

Since certain changes may be made in the above construction and difl'erent embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all the generic and 25 specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

l. Ina Diesel engine, a plurality of cylinders, a plurality of respective sleeve valves, a plurality of respective fuel injector pump pistons, and respective means for oscillating and reciprocating each of said valves, said oscillation and said reciprocation being simultaneous, said means being also in the form of a cam for reciprocating said fuel pistons.

2. In 9. Diesel engine, a plurality of cylinders, a plurality of respective sleeve valves, a plurality of respective fuel injector pump pistons, and respective means for operating said pistons and for oscillating and reciprocating each of said valves, said oscillating and said reciprocating being simultaneous, said means including cams for respectively operating said pistons, said cams also acting as for respectively oscillating and reciproeating said valves.
